Shooting her in the head right through her open window at point blank range as she tried to leave.

The shooter is behind the guy at the door obscuring the view.

But you look at foot placement (lower left circle) the shooter is clearly in no danger of being hit by the car.

Here’s an eyewitness account from @mprnews.org
